Our project Lesson 2 What did we throw away? Starter • Who can remember what’s going on in the next slide? Get your homework out… Complete your sheet to work out what rubbish we’ve thrown away, then do the bar chart. Make sure you complete the questions. What can we do to help? • How can we reduce the amount of rubbish thrown away? • Prizes for the most imaginative! • You could even have them filmed… What is a plastic? • Another name for plastic is polymer. • If we could zoom in on a polymer we would see that it’s made of a long chain of different particles called monomers. • Watch the video discuss: – What did the girls use as a ‘monomer’? – What did they do to the monomers to make a ‘polymer’? What did they say it’s called? – Do you think it’s easy to reverse the reaction? Making polymers • Watch Ms G do the demo. • How do we explain what is happening in the experiment? • When the two ingredients are added in the correct order, they react to form a polymer Making models of polymers • To make a model of the nylon polymer from the demo, one person should add paperclips of alternating colour, whilst the other person extends the chain away from the mixture. • What do the different colour paperclips represent? Time to be famous… • Make a 2-3 minute film teaching someone what a polymer is. • Use the paper clips as props • Use the whiteboards and pens for captions • Speak clearly!
